WlRE-LATH FASTENER AND STIFFENER.

. ing is a specification.

My invention relates to an improvement in the art of putting wire lathon joists or walls by preparing a surface independent of the lath, towhich the wire lath is to be attached by staples; and it consists of astrip of iron in the shape of three sides of a quadrilateral, whichmetallic bearing-stri p is placed with the open ends on the joists orwalls, and of a stiffening wire bar passing over the said metallicbe'aringstrip and fastened by staples; and the objects are as follows:first, to avoid the use of wooden or inflammable furring-stripsheretofore used between walls and wire lath; second, to hold the wirelath off free and clear from the joists, allowing space for the plasterput upon the wire lath to clinch back of the meshes of the lath, and fora free space between the plastered lath and the walls or joists; third,to afford support for the lath between the joists, so as to resist thepressure of the trowel putting on the plaster; fourth, to pre sent asurface upon which lath can be stretched without the meshes of the lathcatching on any obstruction and preventing the stretchin Figures 1 and 2of the accompanying drawings represent my invention. Fig. 1 shows themetallic bearingstrip with stiifeningbar held by a staple, D, whichstaple also holds the bearing-strip in place, and represents my invention as put on the joists and ready for the lath to be stretched overit. Fig. 2 represents a part of a wall, showing two joists and threemetallic bearingstrips, and also the lapping of the selvage or edges ofthe breadths of wire lath upon the stiffening-bar, just as a wallappears after the lath has been put over the metallic bearing-strips andstiffeningbars.

Fig. 1 represents the metallic bearing-strip A, having sides a a, withthe slot 13 in the face of the metallic bearing-strip running transverseto face of the bearing-strip, which slot is so made that staples may bedriven over it, thus (No model.)

holding the strip to the joists or walls. The face of the bearing-stripcontains the depression 0, running longitudinal of the strip, andaffords a resting-place to fix and hold firm the stiffening-bar c, whichis placed in the depression on the face of the metallic bearing-strip,and is fastened by means of a staple, D, passing over the wire orstiffening bar into the joists or wall.

In Fig. 2, F represents joists upon which the three metallicbearing-strips A A A are placed, and fastened by staples D D D. Inputting the metallic bearing-strips A onto the joists F the stiffeningwire bar 0, which, it must be distinctly understood, runs the entirelength of the wall or building, and is to be cut into such lengthsaccordingly, is then placed in the depression 0 in the bearing-strip Aand the staple D driven over it through the slot B, thus holding bothstiffening-bar and bearingstrip in place. If greater strength isdesired, another staple, D, can be fastened over either end of themetallic bearing-strip, one flange of the staple passing outside thebearingstri p and another flange through the end of the slot B. Othermetallic bearing-strips are then placed upon the joists, according toconvenience, care being taken that one metallic bearing-stri p shall bethirty-six inches (the width of the wire) from the first bearing-strip.The wall or joists are thus all studded with metallic bearingstrips sixinchesapart, or thereabout, according to convenience or strengthdesired, and stiffening wire bars running over the same, and the surfaceis thus prepared for the lath.

The wire lath (which is always thirty-six inches wide) is to be placedupon the surface so prepared and drawn transverse to the direction ofthe joists, butin the same directionin which the stiffening-bar runs,and as the stiffeningbars run over these metallic bearing-strips, whichcan be placed on the joists where de sired, there will be astiffening-bar running under the edge or selvage of each breadth of wirelath, and the next breadth of wire lath lapping over the one alreadyplaced is stapled over the same stiffening-bar, thus affording a supportto the joining edges of breadths of wire lath. The said stiffening-baralso serves the purpose of keeping the meshes of wire lath from catchingin the metallic bearing strips or other obstacles while being drawn overthe surface, prepared as aforesaid.

The wire lath can be on in the same direction as the joists wherejoi'sts come every thirty-six inches (the Width of the wire;) but, asthis seldom oeeurs,thestiifeningbar provides a means for putting on thewire lath transverse to the joists, and in all cases, howeverirregularly the ID joists are laid, affords a strong foundation for theWire lath.

hat I claim as my invention is- In awire-lath fastener and stiffener,the combination of a metallic bearing-strip having a transverse slotwith a longitudinal, depression I5 the bearing-strip and stiffening-barto thejoists 20 or wall, substantially as described.
